I love your garden! I'm an avid gardener and I'm in the process of building a rose arbor in the middle of my "spacious" backyard. Which really means it's too huge to do much but subdivide it into smaller areas and "garden rooms".
I have a book on cottage gardens and will be working designing those this summer to prepare the beds come fall when I do my bulb planting. I'm always thinking a couple of seasons ahead. The only thing I do more than gardening is knitting
